A visual interface for a PTT user terminal displays user images of
participants in a PTT conference. When a PTT conference is established, a
controller determines whether an image associated with each participant
invited to the PTT conference is stored in memory on the user terminal.
For each participant that has an associated image stored on the user
terminal, the controller displays the image. For those participants that
do not have an associated image stored on the user terminal, the
controller generates and sends a request for the image. Upon receipt of
the image, the controller displays the image on the user terminal. During
the PTT conference, the controller alters the appearance of the images to
show the status information of each participant, such as which
participant has floor control and presence of participants.
